不過因為預設的apt-get相關設定有時會抓不到套件，所以在要進入chroot前
Copy resolv.conf and sources.list from the host system
# cp /etc/resolv.conf jaunty/remaster/etc/Preserve original sources.list
# cp jaunty/remaster/etc/apt/soures.list jaunty/remaster/etc/apt/soures.list.backup
# cp /etc/apt/sources.list /jaunty/remaster/etc/apt/exit後，replace the sources.list with the original sources.list
# cp jaunty/remaster/etc/apt/sources.list.backup jaunty/remaster/etc/apt/sources.list
